ExploreAbout this exam
The American Board of Obstetrics and Gynecology Reproductive Endocrinology and Infertility subspecialty examination is the certifying assessment for obstetrician-gynecologists who have completed accredited REI fellowship training and wish to be board certified in the subspecialty. It is designed for physicians already grounded in general ob-gyn practice who now manage complex endocrine, infertility, and reproductive surgical problems. Content spans the subspecialty's full breadth, from neuroendocrinology and ovulatory dysfunction through assisted reproduction, male factor infertility, early pregnancy loss, menopause and hormone therapy, pediatric and adolescent gynecology, reproductive genetics and preimplantation testing, contraception and reproductive tract infection, fertility preservation, minimally invasive reproductive surgery, and the ethics and professionalism that frame practice. Preparation is best built around a structured reading plan in current subspecialty textbooks and society guidance, with active recall and case-based reasoning rather than passive rereading. Because the examination tests applied judgment, practicing with vignette-style multiple-choice questions and reviewing each explanation - correct and incorrect - is the highest-yield activity. Candidates should confirm all logistical details, including current format, scheduling windows, and any eligibility or retake policies, directly with the Board, which publishes the authoritative and most current information on its website.

What you'll study
About ABOG Reproductive Endocrinology and Infertility preparation
What is the format of the exam?
It is a computer-delivered, multiple-choice examination built around clinical vignettes, with single-best-answer items covering the subspecialty's domains. The Board publishes the current item counts, timing, and any section structure on its website, and those details change over time, so verify them there before you schedule.
How difficult is it, and what score do I need to pass?
It is a subspecialty certifying examination, so it assumes fellowship-level depth rather than general ob-gyn knowledge, and many candidates find the applied-management items hardest. The passing standard is set by the Board and is not a fixed public percentage; consult the Board for the current standard rather than relying on secondhand numbers.
If I fail, can I retake it, and how soon?
Retake eligibility, waiting periods, and any limits on attempts are set by the Board and can change. Check the Board's current policies before assuming a timeline. In practice, candidates who retake successfully usually rebuild a study plan around their weakest domains rather than repeating the same routine.
How much time should I plan for preparation?
Most candidates spread preparation over several months alongside clinical work, front-loading the broad domains and reserving the final weeks for vignette practice and weak-area review. There is no single correct schedule; track your own accuracy by domain and let that drive how you allocate remaining time.
What study order works best?
Start with the foundational endocrine and ovulatory physiology domains, since they underpin assisted reproduction and infertility management. Then move to clinical domains such as male infertility, pregnancy loss, and menopause, and finish with genetics, fertility preservation, surgery, and ethics. Interleave question practice throughout rather than saving it for the end.
What are the most common reasons candidates underperform?
Three recur: shallow physiology that collapses on applied vignettes, uneven coverage that leaves low-weight domains unstudied, and passive reading without testing recall. A fourth is misreading the question stem, particularly items asking for the next best step versus the diagnosis. Practicing under timed conditions addresses the last two.
Should I use question banks or textbooks?
Both, in that order of priority late in preparation. Textbooks and society guidance build the framework; vignette-style questions expose gaps and train the reasoning the exam rewards. Whichever resources you choose, review every explanation, including for items you answered correctly, because reasoning errors often hide there.
How do I keep up with changing guidance during preparation?
Anchor on current subspecialty society guidance and textbook editions, and note where they diverge, since exam content generally follows contemporary practice. Avoid relying on older summaries. When a fact is genuinely unsettled, understand the reasoning on both sides rather than memorizing a single answer.
Where do I confirm eligibility, fees, and scheduling?
Only with the American Board of Obstetrics and Gynecology. The Board publishes current eligibility requirements, application deadlines, fees, scheduling windows, and retake rules on its website, and those figures are updated periodically. This page is an independent study resource and does not administer the examination or set any of those policies.
